BOAT.

Specification of Letters Patent.

Patented Feb. 16, 1915.

Application filed August 5, 1914. Serial No. 855,176.

To all whom it may concern Be it known that I, HORACE MmDAUoH,a citizen of the United States of America, and a resident of the city of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Boats, of which thefollowing is a specification.

My invention has for its primary aim to provide a scow or boat which will automatically dump its load by a tilting action and subsequently return to its normal position.

Further objects reside in the provision of a boat wherein water may be admitted for tilting the body; an air compartment for returning the boat to its normal position and thereby effect a bailing of the boat; means for limiting and adjusting the tilting of the l oat; and automatic means for releasing the load from the boat.

For a full understanding of the invention, reference is tobe had to the following specification and the accompanying drawing, and those features of construction, arrangements and combinations of parts on which I desire protection will be succinctly defined in the appended claims.

Referring to the accompanying drawing wherein like numerals of reference indicate like partsthroughout: Figure 1 is a transverse sectional view of my improved scow.

Fig. 2. is a side elevation thereof with the center portion omitted, and Fig. 3 shows, in end elevation, my scow in tilted position.

Referring more in detail to the drawing, and using similar characters of reference for designating corresponding parts throughout, 1 denotes the body of the boat which is composed of superposed water and air compartments 2 and 3 divided by partition floor 4.. This floor is disposed at a slight inclination to expedite the bailing of the water through side ports 5, air being conveniently admitted to the water compartment 2 through hatch 6 formed in the load supporting floor or deck 7. Valves 8 having rack extensions 9 for establishing an operative connection through pinions 10 with operating members 11, control ports 5 which latter are above the water line when the boat is without a load. When desirous of dumping the load, the valves 8 are moved to uncover ports 5 for the admission of water into compartment 2. j The tilting movement may be governed by the partial or complete uncovering of ports 5, as is obvious.

A float 12, swingingly secured by its arms 13 t0 brackets 14 on the deck, is limited in its movement by an adjustable member 15 which has its opposite terminals secured to the float and deck, respectively. This device limits the tilting of the boat, the inclination of which may be varied by adjustment of the restraining member 15. A series of doors16, swingingly interposed between posts 17, are provided for retaining the load until the boat is tilted at a suflicient angle, when the latches 18 on the doors are lifted by the float 12, through cables 19, for releasing the doors. The cables are slightly shorter than member 15, for obvious reasons. The door posts 17 constitute supports for the float when the boat is in its upright position.

The foregoing detailed description has been given for clearness of understanding only, and no undue limitation is to be understood therefrom, but the appended claims are to be construed as' broadly as is permissible in view of the prior art.

Having thus described my invention what I claim as new, and desire to secure by Letters Patent of the United States of America, is:

1. In a structure of the character described, a boat body adapted for tilting, and relatively movable means for limiting the tilting thereof.

2.. In a structure of the character described, a boat body adapted for tilting, and adjustable float means for limiting the tilting thereof.

3. In a structure of the character described, a boat body capable of being tilted, a float movably mounted thereon for limiting the tilting of the boat, and means for adjusting the movement of the float.

4. Ina structure of the character described, a boat body capable of being tilted, a float movably mounted thereon for limiting the tilting of the boat, and an adjustable connection between the float and the boat for limiting the movement of the former on the latter.

5. In a structure of the character described, a boat body adapted for tilting, a door for retaining the load on the boat during tilting movement of the latter, and means operable independently of the load for opening the door to release the load.

6. In a structure of the character de- I scribed, a boat body adapted for. tilting," a---' door for retaining the load on the boat during tilting movement of the latter, and.
